Cable Manufacturing Processes Are Changing: No-Binder Yarn, Integrated Machines, and In-Line Inspection – Can Your Equipment Keep Up?

发表评论 / Company Progress / 作者：

Over the past decade, the production process for loose-tube cables has remained relatively fixed – coloring, secondary coating, stranding, binder yarn application, sheathing – step by step. But in the last couple of years, cable manufacturers have started asking themselves: can we skip some of these intermediate steps? Can we make lines run faster, take up less floor space, and produce less scrap?

So, new processes are emerging – no-binder-yarn cables, combined stranding-and-sheathing integrated machines, UV-LED curing. New processes mean that cable equipment manufacturers must evolve too.

The “Invisible” Details in Fiber Optic Cable Equipment Manufacturing: From the Differential Gearbox to the Laser Diameter Gauge

发表评论 / Company Progress / 作者：

When cable factories buy equipment, they’re not buying hunks of metal – they’re buying precision, stability, and years of trouble‑free operation.

The core of an SZ stranding and cabling line is the differential gearbox – a cluster of meshing gears rotating forward and backward, tens of thousands of cycles per day. The quality of the differential gearbox directly determines how many years the stranding machine will last and whether the pitch stays accurate.

The core of a fiber optic cable sheathing extrusion line is the laser diameter gauge – if the sheath outer diameter deviates by just 0.01 mm, it detects it and automatically adjusts. The sensitivity of the gauge directly determines whether sheath concentricity can reach above 98%.

These “invisible” details are what make cable equipment truly valuable.

The Core of Fiber Optic Cable Equipment Manufacturing: The “Metal Core” Inside the Differential Gearbox and the “Eyes” on the Sheathing Line

发表评论 / Company Progress / 作者：

In 2025, the journal Wire & Cable published a paper on the design of high‑speed stranding and cabling units. The paper pointed out that traditional stranding units in high‑speed cabling processes have shortcomings in speed, durability, accuracy, and digital interconnectivity – issues that need to be addressed through the adoption of new servo motors, optimized mechanical structures, improved materials, and enhanced informatization.

Behind this paper lies a technological upgrade that the fiber optic cable equipment manufacturing industry is undergoing.

Fiber Optic Cable Equipment Manufacturing 2026: How AI Data Centers Are Rewriting Technical Standards for Stranding and Sheathing Equipment

发表评论 / Company Progress / 作者：

In its industry trends report released early this year, the UK-based Commodity Research Unit (CRU) pointed out that the optical fiber and cable markets are undergoing simultaneous transformations in multiple directions – AI-driven data center investment has rapidly emerged as the strongest growth engine, while traditional telecom demand has slowed in several markets. The supply landscape is also shifting, with Chinese fiber and cable manufacturers systematically expanding overseas.

While demand surges, supply lags significantly behind. CRU estimates a global supply-demand gap of approximately 16.4% for fiber optic cables in 2026. Against this backdrop, cable prices continue to rise, overseas orders are already booked through 2028, and cable manufacturers have a strong appetite for capacity expansion – directly driving procurement demand for optical cable manufacturing equipment.

Demand has changed. Products have changed. The equipment that makes cables must change too.

The Explosive Demand for Fiber Optic Cable Equipment: How AI Data Centers Are Reshaping the Selection Logic for Stranding and Sheathing Equipment

发表评论 / Company Progress / 作者：

In 2026, the global fiber optic cable industry is undergoing a profound transformation driven by AI. AI computing power demand is fundamentally rewriting the market landscape for optical cables. A single hyperscale AI data center requires several times more optical fiber than a traditional data center. In 2025, global data center fiber optic cable demand surged 75.9% year‑on‑year, reaching 69.6 million fiber‑km; in 2026, this figure is projected to reach 91.6 million fiber‑km. CRU forecasts that over the next five years, the compound annual growth rate for AI‑ and data‑center‑related cable demand will reach 32.6%.

Cable prices have soared in tandem – G.652.D bare fiber prices have risen to RMB 83.4 per fiber‑km, an increase of over 400% year‑on‑year. The popular G.657.A2 specialty fiber has skyrocketed from RMB 32 per fiber‑km in 2025 to RMB 240 per fiber‑km – a staggering 650% increase. General Administration of Customs data shows that in March 2026, China’s fiber optic cable exports reached USD 245 million, up 263.84% year‑on‑year. Many leading manufacturers have orders booked through 2027 and 2028.

The demand structure has changed, the products have changed, and the logic behind selecting optical cable manufacturing equipment must change with them. This article starts with the new requirements AI data centers place on cable products and breaks down the new selection logic for stranding and sheathing equipment.
